Heap Fundamentals Heap sort is a tree-based selection algorithm that treats records as a complete binary tree stored sequentially in memory. The algorithm leverages the intrinsic relationship between parent and child nodes to find the maximum or minimum key value from an unordered sequence. Heaps come in two varieties: max-heap and min-heap. A ...

Heap Sorting Given a unsorted array, heap sort transforms it into a descending sequence: Convert the array into a max heap using heap insertion or heapify operations Repeatedly swap the root element with the last position, reduce heap size, and re-adjust Continue untill heap size reduces to zero Heap Construction Methods Forward Traversal wit ...

Selection Sort Core Concept During each iteration, the element with the smallest (or largest) key is identified from the unsorted portion and appended to the sorted sub-sequence. Implementation void selectionSort(int data[], int size) { for (int current = 0; current < size - 1; ++current) { int smallestIdx = current; for ...
